MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 445,134, dated January20, 1891.

Application filed March 5, 1890. Serial No. 342,800. (No model.)

To aZZ whom it may concern:

Be it known that we, WILLIAM D. CRONIN and CYRIL l3. ADAMS, citizens ofthe United States, residing at Philadelphia,in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Merry-Go-Rounds, of which the following is aspecification, reference being had therein to the accompanying drawings.I

Our invention relates to improvements in merry-go-rounds; and the objectof our invention is, first, to furnish in a merry-go-round a means bywhich the animals, in addition to their movement of rotation about theaxis of the machine, will be given a movement perpendicular to the floorof the machine, and, second, to furnish an ii'nprovement in the meansfor supporting the revolving platform of the machine.

In the drawings, Figurel is a side elevation of our merry-go-rm1nd; Fig.2, a plan, partly in section, of the same; and Fig. 3, an enlargedcentral sectional elevation of the same.

A is the outer or revolving platform of the merry-gorouml, and l? theinner or stationary platform. The revolving platform A is carried byradial arms 0, the inner ends of which are bolted to a hub D, theinterior of which is furnished with teeth E, with which a toothed wheel.F gears and by means of which and an engine or other convenient sourceof power (not shown) the hub D, the radial arms and the platform. A maybe driven.

G is a circular channelshaped casting or track bolted to the arms 0, andII a similar casting or track suitably secured to the floor or ground.In this latter are placed a number of balls I, and the track G restsupon these balls, as shown in Fig. These balls carry the weight of theplatform A and its attached parts, and when this platform is revolvedthe balls turn with it,and the friction is thus reduced to minimum, andby arranging the tracks with the grooves facing each other and placingthe balls Within the grooves lateral displacement of the platform isprevented, as before this can happen the entire platform must be raisedsufficiently to let the balls out of the lower channel or groove andalso let the lowermost edge of the upper track pass over the tops of theballs.

Instead of but one pair of tracks, as we have shown, two or more pairsand their'balls may be used.

The animals carried by platform A have not only a movement around withthis platform, but are also given avertieal movement, so as to have theappearance of running. This vertical movement is given as follows:

J is a circular track bolted or otherwise secured to the floor orground, and the upper side of which is made with a number of curves orcams K, as shown in Figs. 1 and 3. The animals L have their hind legssecured to the platform A by hinges M, and from their forward parts arod Nextends downward through the platform A, and is furnished at itslower end with a roller 0, which rests upon the top of the track J. Asthe platform is revolved it carries around with it the animals, and asthe roller 0 is drawn over the curves or cams on the top of track J theanimals are moved up and down and an appearance as of. running is givento them.

In the drawings we have shown but one row of animals; but in practicetwo or more rows may be mounted upon the platform A.

The animals are constructed of cast-iron, which makes them lessexpensive than if made of wood and much more durable.

B y our arrangement of parts we are enabled to place the merry-go-roundeither out of doors or in a room with a low ceiling, as in practice theplatform A need onlybe elevated ten or twelve inches above the floor,and it is not necessary to do any excavating in order to erect themachine, as the several tracks may be simply laid upon the floor and theupper part of the machine placed upon them, as shown in the drawings.

Ve claim as new and desire to secure by Letters Patent- 1. In amerry-go-round, the combination, with radially-arranged arms, of arevolving platform secured to said arms at their outer portions, a hubsecured to the inner ends of the arms, a circular grooved track securedto the under side of the arms, a correspondinglygrooved track beneaththe first track, balls running in the grooves of the said tracks, and astationary platform Within the revolving platform and over the hub andthe inner ends of the arms, substantially as described.

2. In a 1nerry-go-round, the combination, I with a'revolving platform,of the animals or supports for the riders, arranged thereon in a circle,each of said supports being hinged'to the platform at one end, acircular cam-shaped track below the platform, a rigid rod for eachWILLIAM D.
